ScanOwl
Read full descriptionHide full description
ScanOwl is a private document workspace for scanning documents and IDs, importing PDFs and images, adding signatures and watermarks, extracting text, organizing pages, and exporting clean files. Every scan comes out flat and straight: tilted shots square themselves up, page edges snap precisely into place, and crease shadows or uneven lighting lift away for a clean, copier-white page — with a quick corner check before you save. Merge, split, compress, reorder, convert, or protect documents from one app. Document contents, scans, signatures, and OCR text are processed on your device and are not uploaded to our servers. With your permission, ScanOwl sends optional usage, diagnostic, and subscription analytics with random app identifiers to its Cloudflare-hosted operations service and RevenueCat. You can turn this off at any time in More settings; declining does not affect scanning or purchasing. Apple processes payments. RevenueCat processes the subscription identifiers, purchase history, and access status needed to validate and restore purchases. ScanOwl Pro is available through auto-renewable subscriptions. Available plans, billing periods, local prices, and any eligible free trial are shown in the app and confirmed in the App Store purchase sheet. A trial is available only when your Apple ID and selected plan qualify. Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in App Store account settings. Pro includes multipage scanning, OCR, unlimited exports, and a clean ad-free document workflow.

Scan PDF: Document Scan & OCR turns your phone into a powerful document scanner. Everything runs on your device, and it works offline. SCAN ANYTHING Automatic edge detection and perspective correction give you sharp, flat scans of documents, receipts, ID cards, whiteboards and notes. Auto / Grey / Black-and-white filters plus a brightness slider make every page as clean and readable as print. MAKE A PDF INSTANTLY Export multi-page PDFs (A4 / Letter / fit-to-image), tune compression to keep files small, then share to Gmail, Drive, Messages — or print directly. Lock a PDF with AES-256 encryption. Add your own watermark, timestamp and footer (name + logo). OCR — EXTRACT AND SEARCH On-device OCR pulls editable text out of your scans, in Latin scripts plus Chinese, Japanese, Korean and Hindi. Copy it, share it, or search your whole library by what is written inside your documents. On export, keep the photo and add an invisible searchable text layer, or rebuild the page as selectable vector text — razor sharp at any zoom and remarkably small. SCAN QR CODES AND BARCODES Read QR codes and barcodes on device; open links straight from the result. MERGE, SIGN AND ORGANISE Combine several PDFs and images into one file. Sign and annotate by hand, reorder pages, rotate, delete the ones you do not need, and export any page to your photo library as JPG or PNG. Keep everything tidy in folders with instant search. YOUR DATA STAYS ON YOUR PHONE Every scan, OCR pass and PDF is processed on your device and never uploaded to our servers — no account, no cloud sync, works in airplane mode. Lock the app with a PIN or Face ID / Touch ID, and protect any PDF with AES-256. Available in 17 languages, including English, Tiếng Việt, 简体中文, 日本語, 한국어, Español, Português, Bahasa Indonesia, हिन्दी, العربية and more. The free version is ad-supported; our advertising partners may use your device identifier. Download Scan PDF: Document Scan & OCR — a simple, private scanner that just works.
